Short, steep and tough, the 13-kilometre uphill time trial test from the textile city famous for Ermenegildo Zegna's fine wool fabrics. Uphill all the way, Stage 13 gains 734 metres at an average grade of 5.8% and the steepest pitches of 13%. This is a tough climb but the short distance will limit the time differences between the Giro contenders, and it's a perfect opportunity for Cunego to strut his stuff.
